Lens Overview — Sigma 50mm f/1.2 DG DN
Key Features — Sigma 50mm f/1.2 DG DN
F1.2 Maximum Aperture: Exceptionally wide aperture gathers more light for low-light shooting and produces pronounced subject separation with shallow depth of field.
50mm Full-Frame Coverage: Standard focal length covers the full 35mm frame, making it well-suited for portraits, street, and documentary photography.
Mirrorless-Native Design: Engineered specifically for mirrorless systems rather than adapted from DSLR optics, allowing for a shorter flange distance and optimized optical performance.
Sony E & L-Mount Compatible: Available in both Sony E and L-Mount versions, covering major mirrorless ecosystems including Sony Alpha, Leica SL, Panasonic S, and Sigma fp bodies.
High-Speed Autofocus: Stepping motor-driven autofocus delivers fast, quiet, and precise focus acquisition suited to both stills and video work.
11-Blade Aperture Diaphragm: Produces smooth, circular bokeh in out-of-focus areas across a wide range of aperture settings.

Description — Sigma 50mm f/1.2 DG DN
The Sigma 50mm f/1.2 DG DN Art is a full-frame, mirrorless-native prime lens available in Sony E and L-Mount configurations. Its f/1.2 maximum aperture makes it one of the faster options in the standard focal length range, well-suited to photographers who regularly shoot in challenging light or who want precise control over depth of field. The 50mm focal length falls squarely in the standard range, offering a natural perspective for a wide range of photographic applications.
Both autofocus and manual focus are supported, giving users control over how they want to operate the lens. The 82mm filter thread accommodates standard large-diameter filter accessories. Weighing 1,090g, this lens has a substantial build, which is consistent with the engineering required for a full-frame f/1.2 prime.
Note that there is no built-in image stabilization, so reliance on camera body stabilization systems will be necessary for handheld work in lower light.
